## What it is
uCrop is an open-source Android image cropping library by Yalantis offering flexible cropping, rotation, scaling, and compression with a builder-style API. It is widely adopted (12k+ stars, used in apps like Discord and SoundCloud) and supports a native variant to preserve image quality.

## Use cases
- crop profile photos in an android app
- let users crop and rotate images before upload
- crop images to a specific aspect ratio on android
- compress and scale images in an android app
- add an image editing screen to an android app
- preserve image quality when cropping photos

## When to choose
- you need a battle-tested, widely adopted Android cropping library
- you want flexible rotation, aspect ratio, and compression options
- you need a lightweight integration via a builder API

## When to avoid
- you need image editing beyond cropping/rotation (e.g. filters, drawing)
- your project is not Android/Java-based
- you require a license with explicit terms (repository has no license file)
